There are some setting in system preference, which are related to user interface and could be useful to have an ability to set it for each user separately and use global preference as fallback only. For example: StaffLangSelectorMode AudioAlerts intranetbookbag IntranetCatalogSearchPulldown viewISBD viewLabeledMARC viewMARC hide_marc IntranetBiblioDefaultView advancedMARCeditor CircSidebar ExportCircHistory previousIssuesDefaultSortOrder todaysIssuesDefaultSortOrder EnableSearchHistory numSearchResults defaultSortField defaultSortOrder displayFacetCount expandedSearchOption NumSavedReports And in the future the cash register from Bug 11373 There could be admin page where the system administrator could enable/disable the settings for users and then in users menu could be new item - interface settings where users could change their preferences.
This would be very helpful, especially in large and consortial libraries. Lisette
